Question
What are the various ways to save the environment from excessive plastic wastes?
✓
Answer
Plastic is non$-$biodegradable. It takes several years for plastic to decompose and it is not environment friendly. It causes environmental pollution. Following are the ways to save the environment from excessive plastic wastes:
$-$We must try to Reduce, Reuse, Recycle and recover the use of plastic items. We must develop the habits which are environment friendly.
$-$We must not throw plastic in the water bodies or on the roads.
$-$We must take a cotton carry bag or a jute bag while shopping.
$-$We must try to minimize the use of plastic materials. For example, we must use a steel lunch box or steel containers instead of plastic ones.

Three objects, 1, 2, and 3 of the same size and shape but made of different materials, are placed in the water. They dip to different depths as shown in the figure.
If the weights of the three objects 1, 2, and 3 are w1, w2, and w3, respectively, then
(i) w1 = w2 = w3
(ii) w1 > w2 > w3
(iii) w2 > w3 > w1
(iv) w3 > w1 > w2
